Why can t some mobile phone Bluetooth pairings?

Any mobile phone can be connected as long as it has Bluetooth, but the method is different, and sometimes there are other reasons to connect, and you can't send songs! I think the general brand machine thinks that Bluetooth is easy to use, and the method will be used, I won't say it, what you said can't be connected must be domestic! Big screen,I couldn't find it at first、Can't connect,Then I figured it out myself,First of all, make sure that the file information in the phone doesn't save too much,I've changed my phone now.,The specific connection seems to remember:

Transmit Bluetooth from the file management surface, detect it yourself, and wait for a long time after the mobile phone turns on the bluetooth, and then I know: when you can't find the device, first turn off the Bluetooth of another mobile phone, let your mobile phone find the device first, and then turn on the Bluetooth of the mobile phone in seconds, repeat it several times, that is, you will definitely be able to find it!

in Bluetooth"My device"In the menu, delete the paired ones and re-pair them.

Successful pairing means that the connection is on, and the files cannot be transferred, and there are many reasons. One is that there may be two versions of Bluetooth that are different, the low version generally cannot read the content of the Bluetooth phone with a high version, the second is that there may be restrictions on the security settings of the mobile phone (the default is generally limited), and the third is that different models of mobile phones have different permissions for Bluetooth reading and transmission.

I think that the Bluetooth function is the chicken rib of the mobile phone, so don't use it.

Answer, support me.
